SPECIFICATION forming part of Letters Patent No. 641,009, dated January 9, 1900.

Application led March '7, 1899. Serial No.708 ,130. (No model.)

fo all whom it may concern:

Be it known that I, CHARLES GULLAND, a citizen of the United States, residingat Pittsburg, Pennsylvania, have invented certain new and useful Improvements in Valves, of which the following is a specification.

My invention relates to valves for faucets, tanks, and the like of that class in which there is a valve-casing containing a valve, the valve being interposed between the inlet and the outlet, said valve being held to its seat by the force of water, and the action of said valve controlled by a supplemental valve adapted to relieve the pressure above the main valve, and thus allow it to act.

The present invention relates to the details of construction by which the parts are simplified and whereby also the valve may be adjusted to allow for different pressures of water, and thus the discharge of water may be readily regulated. Y

In the accompanying drawings, Figure l is a sectional View of theinvention, while Figs. 2 and 3 are details, the one of the valve and the other of the cap for the valve-casing.

The valve-casing is shown atA and has an outlet B at its bottom and an inlet C entering the side of the casing below its center. As a valve I prefer to use a rubber ball, which closes the outlet and is directly in line with the inlet. The ball lits the casing loosely, and in operation the pressure of water exerts a force upon the upper side of the ball and keeps it closed. In order that the water may have easy access to the space above the valve, I prefer to cut a notch in the periphery ofl the ball at c, and this allows the water to flow readily to the upper side of the valve.

In order to relieve the pressure from the upper side of the valve, an outlet b is provided, and this is controlled by a supplemental valve o, which may be controlled by hand or by a oat, as may be found desirable. This valve consists of a spindle 2, iitted within a case 3, secured to theV wall of the main casing. The spindle serves to prevent the egress of the Water through the outlet b when raised by the stem of the float, as shown at 5; but when the Heat lowers the spindle falls with it,`and this allows the water to flow out of Ythe outlet l) and around the spindle.

As soon as the pressure is relieved above the valve by the opening of the supplemental being shown at E, and in the center of this cap on the under side I place a screw, which is adjustable so as to `bring it in a different relation to the ball-valve. When it extends downwardly to its greatest extent, it will be seen that it will limit the upward movement of the valve, and consequently reduce `the discharge in cases where the pressure is very great; but where the pressure is slight the screw e may be moved inwardly, so as to a1- low greater movementof the main valve, and thus increase the flow.

l. In combination with a valve-casing', an inlet and discharge opening, a space above the valve adapted to be filled with water and a groove in the wall of the valve to permit the water to flow to the upper side thereof,- substantially as described.

2. In combination with the valve-casing, a main valve therein, inlet and outlet openings,a solid and imperforate cap for the valveoasing and an adjustable screw carried by said cap for regulating the movement of the main valve In testimony whereof I affix my signature in presence of two witnesses.

CHARLES GULLAND.
